Letters Patent No. 111.938, dated February 21', 1871.

IMPROVEMENT IN ROQFING-TILES.

The Schedine referred to in these Letten atont and making put of the um.

perY surface. and near the upper end', said har D fitting into the groove D' formed in the under surface and across the tile which is placed in the course above, said grooveaud bar preventing the water passing above the tile and causing a leak.

The second part of my invention relates tothe combination of the groove D and bar D on" the tiles with the groove O, which is formed longitudinally near the edge of the tile B, said groove C receiving a roundA tongue, C', formed on the under side and ou the edge of the tile A, making water-breaks, and Apreventing the water from passing over theedge or top lo f the tile and causing a leak; also, the parts marked E, which' are sunk into the under-side surface of the tile, saving material and allowing ventilation for the roof-boards, the vribs F forming a bearing for the tile on the roofhoards. Fig. III in the drawing shows their position.

Figure I in the drawing shows the position ofthe tile on the roof and the relative situation of the bars and grooves.

Figure II, a longitudinal section of the tiles, showing the horizontal bars and grooves.

Figure III shows a cross-section of the tiles, and shows the relative position of the longitudinal grooves andil tongue; also, the sunk portion E in the under side ofthe tiles, and the ribs F.

At B is shown a roofing-tile, having on its upper surface, and near the end which is placed uppermost on the roof, a horizontal bar, letter D, which fits into a horizontal groove, letter D', formed into the underside snrface of the tiles, and showuin/Figs. I and II. The object of this bar and groove is to prevent the water from passing over tne upper end ofthe tile and forming a leak.

0n both edges of the tiles B are longitudinal grooves,

O, formed in the upper surface of the tiles, said grooves receiving a longitudinal bar or tongue, O', formed on .the under-side 'edgevof the tiles A, which, by litting into ea'ch other, form a water-break and prevent the Y water from passing over the edge of the tiles. The

position ofthe grooves O and tongues C are shown in Fig. III.

ln Fig. III is also shown the sunk portions in the under side of the tiles, said sunk portions economizing material, make the tiles lighter,and allowing of ventilation.

The ribs F form a bearing for the tiles on the roof.

The novelty in my improvement consists in the horizontal bar D on the upper surface of the tile, and the groove D' formed in the underside of the tiles; alsoz the combination of the above-mentioned grooves and ribs` with the side longitudinal grooves C formed in the upper edges of the tiles B, and the longitudinal tongues or bars O formed in the under-side edge of the tiles A.; also, the sunk portions E ou the underside edge of the ytiles and ribs F.

What I claim as my invention, and desire to secure by Letters'Patent, is

The tileA, provided with the cross-bars D, grooves D', sunken portions E E, and .ribs F F F, in combination with the tile B, provided with the cross-bars D, grooves D', and longitudinal grooves O, and tongues C', when said parts are constructed and arranged with relation to each other, as and for the purposev as herein set forth.

CHARLES HOWARD.
